opportunity to go o in and seeee what he h. -aftfter five momonths on ththe, we got authorization to tap his telephone lines. and to g go inside o of his hoe and dodo a covert t search. doing a covert or surreptitious entry into a home is a very complicated affair. it's not like the ninja movies you see. -thehere was a l local park k te had set upup the command post i. that was the brains of the operation. that's w where it all was going to, , basically,y, be coordinated from. and i remember pulling into the park and kind o of taking in the visual scene. they had these majestic trees. i wawas the firsrst one ther. and i woululd be lyingng if i saiaid that i w wasn't ner. -we had to be absolutely certain that w we were ablble to g get into ththe house, search t the house,, and geget out of t the house without t being caugught. in o order to dodo that, we needed d to make susure thae realally fit intnto the naturl papatterns of f that neighghbo. the fbi wewent to farr as to o obtain a v van ththat lookedd just likike chi mak'k's van that we used to approach the home. the idea being if a neighbor were to look out, they would just assume that chi mak was coming home and would go back to sleep. -you need a huge number of people watchingng the neighghborhoo, making sure somebody doesn'n't walk up p on you by accidenent. you've gotta watch out foror dos and teenagagers, as s strange as s it may souo. teenagagers can cocome and go at anyny time of t the night, and the e dogs can b be barki. neighbors s get up toto smoke on n their porcrh or use t the bathroom. so it's a very complicicated ballet of controlling when you go in and when you leaeave. you cacan't just come and go. -i r remember ststanding in the comommand post and taking stock of everything going on around me, and ththen realizizing just h how complexex this operen rereally was.. alall of the m moving partrt- any y one of thohose things s , and yoyou're done.e. -when you go inside the house, you u can't leavave a tracee that youou've been there. fofor instancece, if the coffe table is very dusty, you can't scoot something bebecause thenen you've lelt another trail l in the dusus. that if f they realally know ththeir house, they'r're gonna come back and s, "how did that thing get moved?" -and, literally, there was dust on things, and the e fbi would d spray dt to replace t the dust wewe'd md so it cocouldn't be e detecte. ifif you leaveve the room m exy how you u left it -- pretty i impressive. -when we w went ininto chi makak's house, we werere surprisesed at t the amount t of informatn that he had taken and stored in his home. this housese was dense with documents. he had them stacked by the front door, on the kitchen table, in his bedroom, in his computer roroom, a secocond bedroomom -- alall over thehe house. when i i saw that t much inforon in there, , i felt valalidate. a lot of research,h, a lolot of manpopower had gogono this firstst entry into the hou. and this was validation -- ththat, again,n, we werere onto thehe right per, that we hahad a guy who was cocollecting i informat. and ththis is the e informatin thatat we thoughght was at r , ththat may havave already y e to c china or may soooon go to chchina. -t-the search h of the houoe confnfirmed he w was stealing infoformation, but we d didn't haveve the prf that he e was commititting esespionage, and ththat would i include givit toto a foreigngn governmene. we couldld prove thahat he stol, we couould prove t that he trar, but we cououldn't provove ththat he travaveled wiwith the clalassified dodocu. that wasas the next t step. ththat was thehe smoking g n that w we needed t to go to the next l level. -after thehe covert enentry, the nextxt big breakak happend when w we recoverered somemething fromom the trash. -w-we were looking throuough chi mamak's trashh fofor almost a a year bebefore we fofound any real high-value evidenence. -amomongst the t trash, we found a lot ofof tiny littttle pieces s ofr with chinenese charactcters on . -o-on that giviven day, special l agent jessssie murry frfrom the fbibi had, in t the , laid out a a bunch of pieces s of paper,, anand she was s putting them togogether likeke a puzz. and she cacalled me ovover. shshe said, "g"gunnar, cananu hehelp me withth this?" i i remember m making someme e ababout how i i could readad ch. but i caugught the thrhree lets at thehe bottom that said d "ddx," anand i said, , "of courses, that's about the navy's next desestroyer." we translated that note, and the note went from being a note to being a tasking list. whicich clearly demonstratated t chi mak k was receiviving guide or directition to s steal what t he was stete. -a t tasking lisist is someteg ththat the hanandler, ththe foreign n governmentt gives s the indivividual and s, "thesese are the t technologis thatat we want."." anand in his c case, hehe received d two lists.. the other r list wawas typed inin chinese,, specificically telliling him, "c"collect thihis informatatn onon a disc, p put it togeget, and thenen give it t to us." we learneded later thahat the tasking anand instructction shs originateded from chi i mak's handler inin china, mr. pupu pei-liangng. the twtwo sheets w were delived in a an orange-y-yellow healalt. chi mak opened up the book, and inside were these two lists. i thought at the time we were extremely fortunate that chi mak tore up a note that, , if he were stopping and thinking about it, he would have burned or shredded or disposed of in a way that we couldn't have found. very little was ever in his trash, bills s -- that sort of thing. to find that tasking list one time, that wasas one of ththe big miss he m made. whwhen i foundnd those twowo s and i knknew that wewe had a tag listst and a setet of instruruc, that valididated the w whole invevestigation n up to thatat . i knewew nobody wowould questn our r investigatation, that w we were on n the right t. anand i knew g going forwawd that w would meann we wouldld continuee to get r resources toto take it t to its lological concnclusion. ♪ -we were looking through chi mak's trash for almost a year befofore we founund any real high-h-value evididen. -f-finding thehe trash withth the taskiking note and the e instructioion sheet was the momost signifificant fd we had,, 'cause i it showed h he was stl spyiying for chihina. -finding the tasking notes in his trash allowed usus to use momore obtre invevestigative e tools. -during g this invesestigatio, chi mak anand his wife took t three vacatations, whicich gave us s opportunitis toto go into t the home. ththe first opopportunity,, we went into thehe home, and we s saw all thehe paperwk ththat he had d
